T0 aZZ w7wm z't may concern:

Be it known that I, .TUDSON DAVID V AN EUREN, a, citizen 0f the UnitedStates, residing at Sioux City, in the eounty of VVoodbury and State 01:Iowa, have invented cerain new and useful Improvements in Oorn-HuskingMachines, of which the followi'ng is a specification, reference beinghad t0 the accompanying drawings, forming part and pa1cel thereof.

The principal object 1 have in view is to provide a compact andeffective machine that may be mude to traverse the fields of corn, pluckthe ears from the sialks, anti then husk and cleliver the same into areceptacle dravvn alongsicle of 01 attaehed thereto; 01 tl1e machine maybe usecl zus a stationary corn-h usket, if desired.

Referring t0 the drawings, wherein similar letters designate like partsin all the views, Figure 1 represents a plzm view of my new corn-huskingmaehine. parts of the machine broken away, detaehed, ancl enlarged. Fig.5 is a, longitudinal secoional view through the trough at the rear end0f the machine.

'lhose skilled in the art tq which this invention appertains willcomprehend the essential featnres anti mode 0f operation of my inventionf101n a careful scrutiny and cousidemtion of 1;he dmwings, in which Theletter A designates the main fmme.

B is the driving-shaft, provicled Wih suitable supporting-bearings fixedin said main frzmie and carrying 13119 traction-wheel V adjaeent t0 thedrivers seat d", Wl1ile the opposite sicle 0f said main frame A issupported by the Wheel W in the usual manner.

Suitably situated between the main wheel "W a-nd oppositely-placeclsupporting-wheel V are tl1e slightly rearwarclly-converging rollers E,EL11(1 ad j acent 130 the rearwarcl end and running at a 1ight angle tosaid rearwardlyconverging longitudinal rollers E ar'e the transverserollers F. 'lhe rollers E are provided with suitable end bemings fixedtothe supporting transverse ti1nbers of the fran1e A and l1ave spiralgrooves 1unning outwarclly ancl rearward from encl t0 end thereof, andthe forward conical ends 0f said rollers E are provided Withspirally-situaed spikes 01' teeth n, corresp onding with the spirals ofthe rollers.

Figs. 2, 3, and 4 showv Situated adjacent 130 and im mediateiy above theforward end of the husking-rollers E a1e tl1e corn-gahering gears 01reels G, whicl1, as shown in ehe drziwings, intermesh slightly, so thatthe motion of one will be transmitted t0 the other, thereby obviating henecessity 0f providing supplemental mechanisms f01 operating theleft-hand reel, ancl suitablyabove the rearward endsof saidhusking-rollers is the fixed guard and guide H, provided With Eherecurved outwardly-sprea cling wings h, suitably held in place by 1neans0f securingpins h 01 in any suitable manner.

The transverse rollers F have their fixed supporting-bearings in-theelevator-trough K and are inclosed therein A traveling belt 01 apron L,situated above the rollers F, serves f0r elevating sind delivering thehusked corn into a convenienl: truck 01 receptacle at the delivery sideof ehe machine, as indicated in Fig. l. This belt is sl1own in saidfigure broken away t0 disclose saicl rollers, and the corn is preferablyfed onto its upper side neai irs rear end through the fixed qmm-d andguide I-I, and by said belt is carried t0 the bo'utom 0f the trough andthrough said trough 130 the receptacle provided f01 the husked 001n. Itis obvious, however, that if deemed desirable the rear end 0f 'the fixedgnard and guide may be placed in such relation ro the trough as toitself direct the corn into the Same a1; a point adj-acent t0 the 1 9mend of the elevating-rollers, in whi eh case tl1e belt will merelyassist the rollers in elevating the corn from the trough into thereceptaele.

The running height 0f the gathering-gears is adj ustably regulated bymeans 0f the handlever M and quadrant Q,said lever beingeonnected witl1the tongue T, whieh is pivoted to the forward end of the frame by a xod0", the forward end of whicl1 is secured to a plate t, attached t0 tlieupper surfzwe 0f said tongue anal projecting upward therefrom.

The 1node of operation is as follows: M0- tion is imparted to Ehehusking machinery through tl1e driving 01 traction Wheel W, power-shaftB, gear-wheel a, and engaging pinion a -to the trnsverse shaft O,eoacting with other suitable bevelgears, shafts, and pinions as follows:The shaft O has a siight sliding movement in its bearingsin the frame A,whereby the husking machinery may be thrown out of 01 into ge2u, asseen. One means fo1 accomplishing the, throwing int0 and 0ut 0f gea1 ofthe husking machinery is shown in the drawings; but I (10 not wish 130be understood as limiting myself L0 this particul2u means; as anysuitable means f01 this purpose may De adopted without departing fromthe spirib 0f my invention. Said means consists of a lever f, secured atone end to one end of a shaft f", the opposite end 0f which shaft isconnected With a lateh f by means 0f a 10d f, said 1atch hzwing, asshown, a projection f which engages the side 0I:' the bevel gear-wheelb, whieh is on the shaft C. The shaft O 1's encircled by a coil-springX, which tends to keep the said bevel-gear 0ut of engagement withtheother. Frorn the abowa it Will be readily seen that if thehnskingmaehinery is in gear anr1 it is desired t0 throw it 0111 of gear allthat is necessary is to move the 1ever f in a certain direetion t0 causethe latch f 110 be diseng-aged from the bevel-gear b, when the spring XWill drzuv said shaft toward it snfliciently t0 disengage saidbevel-gear from the oher bewl-gear b, and when it is desired to throwthe husking machinery into gear it is 0111y necessary t0 mo've saidleverin the opposite direction, when the latch will be caused to engage saidbevel-gear 011 the shaft O, overcome the tension of the spring 0n saidshaft, an l move said bevel-gear into engagement With the other.Bevel-gears b communicate motion to the rearwmdly-runnin;r shaft D undto the eorn stripping and husking 1011e15 E byn1eans 0f uhe gear-wheel cand pinions d d, fixed on Lhe rear ends of said shaft and rollers,respectively, while a, pinion e, fixed 011 the forward end of the lowershaft D of the elevator, meshes with the adjacent pinion d and givesproper motion to the twin elevator rollers F am]. elevator apron Lthrough the engaging gears e, a e and e* and sprockec-wheels and chain gg, respeetively. A longitudinally-reaehing shaft D runs forwardlydireetly above 2u'1d in a 1ight line With the shaft D, and is providedWith a pinion b 011 its 1ear end, conesponding with an equalengagingpinion of uhe said shaft D, (see Fi n 3,) whereby motion isgiven to the gathering-wheels 01 intermshing right and. left ree1s G oftho upright shafts G through the wenn s, fixed to the forward end ofsa'1d shaf'u D and worm-engaging whee1 s of said upright shaft. Thegathering-wheels, the huskingrollers, the elevator-rolls, apron, am].other moving mechanisms a1e given 1notion by means 0f the main whee1 andtraveling parts, as shown; buu the machine may remain stationary zmd eheoperative parts propelled by means of abe1t 01' shaft deriving its powerfron1 any forma 01 kind 0f motive power at band, as 1's evident.

Othe1 variations 01 modifieations of my invention n1ay be applied bythose skilled in the art, and hence I (10 noo design to confine myselfto the precise construetion shown; but

'What I d0 elaim, and desire t0 secure by Letters Patent of the UnitedStates, is

1. In a corn-husking machine, the internmshing gathering-reels G G,mounted upon verticalshafts,andrearwardly-convergingspirally-groovedhusking and stripping rolls E, extending longitudinally 0f the machineand. provided at their forward ends with spirallyarranged teeth, incombinat-ion with atrough Lt the rem end of 1;he machine, elevating anddelivering; rolls in said trough, an elevatingbe1t above said 1011S, andmeans for operating said p2uts.

9. In a corn-husking maehine, the intermeshing gathering-reels G G,mounted upon vertica1 shafts, spirally-grooved husking and strippingrollers E, and a fixed guard and guide seeured to the 1e2u end 0f themachine and having forwm-dly-projecting wings 10- cated 011 oppositesides 015 the opening between said rollers, in eombination With a troughm the rein end of Lhe machine, e1e' vating and delivering rolls in s-aidtrongh, an elevating-belt above said rolls, and means for operating saidparts.

In test'nnony whereof I hereunto affix my hand and signature, in thepresence of two witnesses this 27th day oft October, A. D. 1890.
